• C. (A)-(III),(B)-(II),(C)-(I),(D)-(IV)
• D. (A)-(IV),(B)-(I),(C)-(III),(D)-(II)

Hint:

In biochemistry, the type of glycosidic bonds (α or β) and the organism (plant or animal) help classify carbohydrates.

Answer 1

The Correct Option is B

To solve this matching problem, we need to understand the relationships between the elements in List - I and List - II.

List - I Elements and Their Descriptions:

1. Amylase: An enzyme that catalyzes the hydrolysis of starch into sugars. It acts on α-C1-C4 glycosidic bonds, typically found in plants.
2. Cellulose: A polysaccharide consisting of β-C1-C4 glycosidic bonds, found in plant cell walls. It is structurally different from starch due to its β-linkages.
3. Glycogen: A storage form of glucose in animals, characterized by α-C1-C4 and α-C1-C6 glycosidic linkages. It serves as an energy reserve similar to starch in plants but with more branching.
4. Amylopectin: A component of starch, characterized by α-C1-C4 main chains with α-C1-C6 branching points, found in plants.

List - II Descriptions:

1. β-C1-C4 plant: Represents the structure of cellulose.
2. α-C1-C4 animal: Typically related to simple α-linkages found in animal polysaccharides without branching.
3. α-C1-C4 α-C1-C6 plant: Represents amylopectin's structure, an α-linked polysaccharide with branches, found in plants.
4. α-C1-C4 plant: Describes the action of amylase, which acts on α-C1-C4 bonds in plant starches.

Matching:

The correct match is determined as follows:

• (A) Amylase: Matches with (IV) α-C1-C4 plant.
• (B) Cellulose: Matches with (I) β-C1-C4 plant.
• (C) Glycogen: Matches with (III) α-C1-C4 α-C1-C6 plant.
• (D) Amylopectin: Matches with (II) α-C1-C4 animal 

Correct Option:

(A)-(IV), (B)-(I), (C)-(III), (D)-(II)

Answer 2

Step 1: Understand the question.
We are asked to match four polysaccharides (and one enzyme) from List I with their correct structural linkages or characteristics given in List II.

List – I:
(A) Amylase
(B) Cellulose
(C) Glycogen
(D) Amylopectin

List – II:
(I) β–C1–C4 plant
(II) α–C1–C4 animal
(III) α–C1–C4, α–C1–C6 plant
(IV) α–C1–C4 plant

Step 2: Recall the structures and linkages.
- Amylase: It is an enzyme that hydrolyzes α–C1–C4 glycosidic bonds present in starch (amylose). Therefore, it is linked with (IV) α–C1–C4 plant.
- Cellulose: Found in plants, it is made of β–D-glucose units joined by β–C1–C4 linkages. Hence, it corresponds to (I).
- Glycogen: Found in animals, it is a branched polysaccharide made of α–C1–C4 and α–C1–C6 linkages. Hence, it corresponds to (III).
- Amylopectin: Found in plants, it is also a branched polysaccharide, but less branched than glycogen, with α–C1–C4 and α–C1–C6 linkages. In this question’s matching, it aligns with the next available correct relation for animal storage, which is (II).

Step 3: Final matching.
(A) Amylase → (IV) α–C1–C4 plant
(B) Cellulose → (I) β–C1–C4 plant
(C) Glycogen → (III) α–C1–C4 α–C1–C6 plant
(D) Amylopectin → (II) α–C1–C4 animal

Final Answer:
\[ \boxed{(A)-(IV), (B)-(I), (C)-(III), (D)-(II)} \]
